Deep Learning Models For Bridge Deck Evaluation Using Impact Echo, Sattar Dorafshan, Hoda Azari

Civil Engineering Faculty Publications

Impact echo (IE) is a common nondestructive evaluation (NDE) method to detect subsurface defects in concrete bridge decks. The conventional approach for analyzing the IE data requires user expertise to define analysis parameters that could hinder broad field implementation. In this paper, the feasibility of using deep learning models for autonomous subsurface defect detection in bridge decks using IE has been investigated. A set of eight laboratory-made reinforced concrete bridge specimens with artificial defects were constructed at the Federal Highway Administration Advanced Sensing Technology NDE laboratory. A total number of 2016 of IE data was collected from these specimens. A …

Draft Genome Of The Common Snapping Turtle, Chelydra Serpentina, A Model For Phenotypic Plasticity In Reptiles, Debojyoti Das, Sunil Kumar Singh, Jacob Bierstedt, Alyssa Erickson, Gina L. J. Galli, Dane A. Crossley Ii, Turk Rhen

Biology Faculty Publications

Turtles are iconic reptiles that inhabit a range of ecosystems from oceans to deserts and climates from the tropics to northern temperate regions. Yet, we have little understanding of the genetic adaptations that allow turtles to survive and reproduce in such diverse environments. Common snapping turtles, Chelydra serpentina, are an ideal model species for studying adaptation to climate because they are widely distributed from tropical to northern temperate zones in North America. They are also easy to maintain and breed in captivity and produce large clutch sizes, which makes them amenable to quantitative genetic and molecular genetic studies of …

The Phonology Of Mbati, Sarah Gloria Lepage

Theses and Dissertations

This description of the phonology of Mbati/Isongo (C13) (mdn) of CAR is based on a word-list recorded by native Mbati speakers. A description of nominal and verbal morphology is included as a foundation for discussing morphophonemic processes. Only open syllables and consonant-glide clusters are allowed. Alveolar and velar plosives are affricated or palatalized before the high front vowel. Prenasalized consonants act as phonological units, rather than clusters. Mid-vowels within noun roots harmonize according to the feature [ATR]. [−ATR]-dominated vowel assimilation occurs within verb stems. Vowel hiatus is resolved by glide formation, diphthong formation, elision, and epenthesis, depending on the vowels …

The Vowels Of Urban Qatari Arabic, Mark Daniel Shockley

Theses and Dissertations

Urban Qatari Arabic is a variety of Gulf Arabic [afb] spoken by Qataris with traditionally sedentary tribal backgrounds. This study examines phonetic and phonological aspects of Urban Qatari Arabic vowels using acoustic phonetic data gathered in Qatar. A new phonemic vowel inventory is proposed, including five long vowels and two short vowels. This finding contradicts published studies on Gulf Arabic, which include three or more short vowels; however, it is not unexpected when studies are compared from nearby Arabic varieties. The vowel inventory is also investigated using four linear mixed-effects regression models. In Gulf Arabic, variation in short vowel backness …

Distinguishing Passive From Mp2-Marked Middle In Koine Greek, Andrew Charles Lamicela

Theses and Dissertations

This thesis seeks to answer the question, How can one determine whether an MP2-marked (traditionally “passive”) verb in Koine Greek is semantically passive or middle? MP2-marked verbs in the New Testament and Septuagint were analyzed in order to determine what factors indicate passive or middle in each case. This thesis argues that both lexical and contextual factors play a role in the determination. Lexical factors include whether the verb has agent-oriented components of meaning, how likely the event is to occur spontaneously, and whether the verb tends to have a subject that is both agent and patient. Contextual factors include …

Information Structure In Soumraye (Somrai), An Eastern Chadic Language, Emily Ruthann Miller

Theses and Dissertations

This thesis examines the information structure of Soumraye, also known as Somrai (common alternative spelling: Soumray; ISO: SOR; autonym: Chibne, Chibné or Shibne), a largely unstudied Eastern Chadic (Afro-Asiatic) language of Central Chad (Eberhard et al. 2020). Analysis is based on four fiction and two non-fiction narratives as well as part of an expository text and some previously published proverbs. I primarily use a framework from Lambrecht (1994). The default information structure of Soumraye is topic-comment or presupposition-focus. The construction for marked topic, or topicalization, consists of a preposed noun phrase ending with the topicalization particle da. Da's …

Resiliency As A Moderating Factor For The Impact Of Adverse Childhood Experiences On Substance Use In American Indian And Caucasian College Students, Emily Sargent

Theses and Dissertations

College students engage in frequent substance use behaviors and experience related consequences. Previous research suggests American Indians (AIs) experience higher rates of substance use and related consequences. Further, AIs may experience negative substance use outcomes given higher rates of adverse childhood experiences (ACEs). However, resiliency (i.e., experiencing positive outcomes despite adversity in one’s life) may be one factor that moderates the relationship between ACEs and substance use to in order to reduce use and negative consequences. The current study examined alcohol and drug use/consequences, ACEs, and resiliency among AI (n = 69) and Caucasian (CA; n= 91) university students via …

Perception And Production Of Nanning Mandarin Fourth Tone, Julie Flaming

Theses and Dissertations

Local varieties of Mandarin Chinese have been underdocumented. This study focuses on Mandarin high falling fourth tone (T4), as pronounced in connected speech by four female speakers native to Nanning City and its surrounding areas, in Guangxi Zhuang Autonomous Region. Surface forms of T4 and the high level tone (T1) often exhibit minimal difference, most likely due to the strong Cantonese influence in the area. I compare the pronunciation of T4 in multiple environments to the predictions about Standard Mandarin T4 surface forms in those same positions. Nanning T4 is flatter overall than Standard Mandarin T4 in all positions, with …

Belief In Pure Evil As A Trait Predictor Of Harsh Judgments Of Perpetrator Attributes, Victoria Charlotte Mary-Rose Pocknell

Theses and Dissertations

Humans look for a quick and comforting explanation for why bad things happen. One popular explanation is to believe good and evil are active forces affecting people and events. Past research suggests belief in evil is associated with harsher judgments and less prosocial behavior. However, little research has explored what factors influence the development of a belief in evil or its effects in an experimental setting. Using a national sample of Amazon MTurk respondents (N = 511), participants completed a series of potential developmental antecedent measures (e.g. personality domains, religiosity, etc.) and viewed a video vignette of a crime with …

Lunar Daytime: Behavioral Experiments In A Space Analog Living And Working Environment, Marc M/ Cohen, Donald Barker, Suzanna Bianco, Sheryl Bishop, Pablo De Leon, Ron Gentile, Sandra Haeuplik-Meusburger, James A. Wise

Space Studies Faculty Publications

The Lunar Daytime concept addresses the challenge to behavioral scientists and architectural researchers in conducting research in space habitats or habitat analogs to produce scientifically valid results. Historically, researchers were limited to largely qualitative surveys. Instead, the Lunar Daytime (LDT) team will demonstrate the efficacy of a modifiable environmental habitat analog laboratory capable of producing empirical, measurable, and quantitative data sets. To measure effects on crew performance and crew behavioral responses as a dependent variable, researchers must be able to make and control changes in the physical living and working environment as an independent variable. Lunar Daytime refers to modeling …

Young Bisexual People’S Experiences Of Sexual Violence: A Mixed-Methods Study, Corey E. Flanders, Raeann E. Anderson, Lesley A. Tarasoff

Psychology Faculty Publications

Bisexual people are at an increased vulnerability for sexual victimization in comparison to heterosexual people, as well as gay and lesbian people. As the majority of first sexual violence experiences happen prior to age 25 for bisexual women, young bisexual people are particularly vulnerable. Despite consistent evidence of this health disparity, little is known about what factors might increase young bisexual people’s risk for sexual victimization, or how they access support post-victimization. The current study addresses this gap through a mixed-method investigation of young bisexual people’s experiences of sexual violence with a sample of 245 bisexual people age 18–25. Quantitative …

Reliability Of The Styku 3d Whole Body Scanner For The Assessment Of Body Size In Athletes, Joe D. Derouchey, Grant R. Tomkinson, Jesse L. Rhoades, John S. Fitzgerald

Education, Health & Behavior Studies Faculty Publications

Anthropometry is important for predicting sport performance. While 3-dimensional (3D) body scanners increase the feasibility of anthropometric assessment, reliability data on athletes are lacking. The aim of this study was to determine the test-retest reliability of a portable, single-camera 3D body scanning system (Styku S100) to assess circumferences, and whole-body and segmental surface areas and volumes of athletes. Forty-nine (19 male) athletes were scanned six times (two sessions of three scans). The Styku scanner demonstrated nearly perfect reliability. Systematic errors were negligible (mean standardized bias [95%CI]: scan 1 vs. 4, 0.04 [0.02, 0.06]), random errors were negligible (mean standardized typical …

Mcgirt V. Oklahoma, United States Supreme Court, Neil M. Gorsuch

US Government Documents Related to Indigenous Nations

This United States (US) Supreme Court case, decided July 9, 2020, clarified the boundaries of Indigenous land within the state of Oklahoma (OK) and, by extension, the limits of Oklahoma’s jurisdictional reach. Following the perpetration of his crimes in 1997, Oklahoma state court convicted Jimcy McGirt of three sexual offenses; however, McGirt contended that the state lacked the jurisdiction to try him for these crimes because he is an enrolled member of the Seminole Nation and because his crimes took place on the Creek Reservation (Muscogee Nation). Oklahoma argued that although an 1883 Treaty established a section of land for …

Temporal Trends In Handgrip Strength For Older Japanese Adults Between 1998 And 2017, Grant R. Tomkinson, Tetsuhiro Kidokoro, Trevor Dufner, Shingo Noi, John S. Fitzgerald, Ryan P. Mcgrath

Education, Health & Behavior Studies Faculty Publications

Objective: To estimate temporal trends in handgrip strength (HGS) for older Japanese adults between 1998 and 2017.

Design and Methods: Adults aged 60–79 years were included. Annual nationally representative HGS data (n=176,449) for the 19-year study period were obtained from the Japanese Ministry of Education, Culture, Sports, Science and Technology. Temporal trends in mean HGS were estimated by sample-weighted regression models relating the year of testing to mean HGS. National trends in absolute, percent and standardized HGS were estimated by a post-stratified population-weighting procedure. Temporal trends in variability were estimated as the ratio of coefficients of variation (CVs).

Results: Collectively, …

Physical Therapy Management For A 16-Year Old Female Following Arthroscopic Plica Resection And Partial Synovectomy: A Case Report, Hannah Brennan

Physical Therapy Scholarly Projects

Background and Purpose. Synovial plica is a common abnormality found primarily in the knee joint. Plicae can become irritated and inflamed with repeated motions causing pain and limited range of motion. Conservative management of symptoms is often the first method of treatment. However, surgical excision is considered if symptoms still persist.

Case Description. The patient is a 16-year-old female referred to physical therapy (PT) for post-arthroscopic management of a left plica resection and partial synovectomy. The patient presented with limited strength, range of motion and increased pain, congruent with her post-operative condition. The patient was seen by PT …
